Been a strange few weeks here. Running a 400W panel setup (2x 200W Victron in series) into a SmartSolar 100/30, feeding a 200Ah lithium.

@SprinterProject makes a good point about the input current limit — that's probably your best first line of defence here.

Compo89 | Posts: 412 @TrevorHughes I'm running something similar - boat plus a static cabin - and the thing that kept me sane was accepting they're fundamentally different beasts rather than...

@MarshSoul check your overcurrent delay setting in the JBD app — mine was factory-set to basically zero, so any inrush spike (inverter, fridge compressor kicking on, etc.) was enough to spook it...

Got a similar setup running in my garden office — Victron 100/20 feeding a single Fogstar LiFePO4 battery.

Jumping in here as someone who made exactly this transition last spring. @MistyTinker and @Curly are spot on about cabling, but what caught me off guard was the BMS communication side when I...

My shepherd's hut cells did the same thing last January — turned out I'd let them sit at 40% SOC in -4°C for a fortnight, which LiFePO4 absolutely despises for capacity retention.
Great timing on this thread — I made the switch last spring on my 60ft trad and haven't looked back.

GlenDoug | 512 posts Worth being precise here — "refusing to bulk charge" and "sitting in float at 60% SOC" aren't necessarily the same fault. If it's genuinely skipping bulk...

Great thread this. @ExTrucker73 one thing worth flagging that nobody's mentioned yet — moisture and corrosion protection is your biggest concern moving from motorhome to marine use.

Reply by Deano13: @BayJason 3kW should be workable for a Leaf depending on your daily mileage. The key thing to remember is you're not charging directly from panels — you're cycling through the...

Great thread, this caught my eye as I went through something very similar last spring. @MarshSoul one thing nobody's mentioned yet — check your BMS firmware version using the Xiaoxiang app (the...

Got a bit of an odd one here. I'm running a 400W solar array on the static caravan with a pair of Fogstar 100Ah LiFePO4s (so 200Ah usable) and a Victron MultiPlus-II 24/3000.

Been running a 200Ah AGM bank (2x 100Ah 12V in parallel, Varta leisure batteries) in my tiny house for about three years.

VanJulie | 📍 Afloat | ⚡ Boat setup Been thinking about this a lot actually — on the boat I've got a dedicated "house bank" that I try not to raid below 30% for exactly this reason, it's...

@DontPanic44 classic calibration mismatch — the SmartSolar measures current at the controller output, while your battery monitor is measuring at the battery terminal.

Has anyone actually measured the real-world difference by temporarily rewiring to parallel instead? I've got a similar Frankenstein situation at my cabin — three panels from different batches...

Hey @MarinePhil, one thing worth considering that nobody's mentioned yet — cable sizing. At 24v you're pulling roughly double the current for the same wattage, so you'll need beefier cabling...

Good shout from @DalesSolar on the flat discharge curve — that catches a lot of people out when they first switch to lithium. What I'd add from my own experience running a Victron SmartSolar on...

@Martin1962 good timing on this build — I went through exactly this with my Sprinter conversion last year. The DCC40S handles it elegantly: it blends both inputs simultaneously rather than...
